Appalachian History: "On September 13, 1916 a five-ton circus elephant was executed, hung from a 100-ton Clinchfield railroad crane car, in the little town of Erwin, Tennessee. ‘Murderous Mary’ had killed a man, and for that she had to die. Shooting her in the four soft spots on her head would be both difficult and dangerous. She wouldn't eat poison. And the town didn't have enough power to electrocute her."
